If you want to make corn high-yield, what are the essentials to master when planting?

The winter climate is cold, and the corn that has experienced the cold winter will enter the dormant period. In the absence of pre-sowing seeds, corn germinates slowly and the germination rate is low. By drying seeds before sowing, the vigor of corn can be well awakened and its germination and emergence can be promoted. Prevention of maize seedling and root diseases. Long-term storage of maize seeds has great potential diseases. When the seeds carry germs into the ground, it will not only affect the health of maize seedlings, but also threaten the long-term health of maize roots. By drying seeds before sowing, ultraviolet rays in the sun can eliminate bacteria and prevent diseases. Seed drying before sowing has many advantages, which will directly affect the emergence of corn and ultimately affect the harvest of corn, so seed drying before sowing can be said to be essential.

seed drying is to promote emergence and high yield, so it is necessary to choose good seeds. If the seeds are inferior, even if the seeds are dried, they can't get a good harvest. Select corn seeds with full grains, and screen out incomplete seeds with symptoms such as blackening. Corn plants have deep roots and luxuriant leaves, and the growing period is mostly under high temperature conditions, which is a crop that needs more water. Corn needs different water in different growth stages, so it is necessary to carry out scientific irrigation according to the law of corn water demand and local climate to meet the water demand of corn in different growth stages, ensure high and stable yield, and achieve the purpose of high efficiency and water saving. In order to ensure the leveling of the land, keep the moisture in the soil and provide favorable conditions for the growth of corn, the soil should be turned loose in time.

when selecting corn seeds, the factors such as soil conditions, humidity, temperature, precipitation and so on should be fully considered. In China, although corn is planted in many areas, due to the differences in environment and region, corn seeds should be carefully selected, rotten seeds and bad seeds should be eliminated, and high-quality seeds should be selected to ensure the yield and quality of corn. Fertilize corn in time, supplement the phosphate fertilizer and nitrogen fertilizer needed by corn to ensure the smooth growth of corn, but pay attention to proper fertilization to avoid damaging the environment and soil. In the maize seedling stage, it is necessary to do a good job in pest control and improve the survival rate of maize seedlings. Rainwater can't provide enough water and nutrients, so proper irrigation should be carried out to keep soil moisture, so as to improve the yield and quality of corn.
